Intensive Care Unit

In one Intensive care unit, people always died on the same bed at 11 am on a Sunday morning, regardless of their condition. This puzzled medical staff, so a group of doctors decided to observe the bed in secret and waited for the fateful hour. Some held crosses and prayer books to ward off evil influences, while the less superstitious had video cameras to catch the whole thing on tape. At the 11th hour, the door to the ward slowly opened, then a cleaner came in, disconnected the life support machine and plugged in a vacuum cleaner.
